Comments:
Shill was observer. Nests X 2 gives the estimate of breeding adults though an actual count may have also been conducted. Four of the adults are non-breeding. Conducted as part of Western Colonial Waterbird Survey (WCWS), a breeding survey of 18 species from May to July 2009 to 2011, resulting in this Atlas. Survey date given here is the only date provided.

Comments:
This was a waterbird study of Laramie Plains lakes. From Table 1, relative abundance which is the mean number of birds per survey. At Laramie Plains lakes, evaporation rates exceed precipitation rates so water levels decline. At one lake, saline soil can salinate water to levels that exceed the ocean. These are not named as specific threats for particular lakes though so was not entered as such.

Comments:
Only grebe observations of reproduction (breeding, etc.) and nesting activity were entered. Observations with coordinates or shapefiles that were not at nor near a significant water body were not included as these might be errors in species or location (Grant Frost pers. comm.). Data from Nesting/Production Survey.
